Abstract

The invention provides a fatigue detection device with reinforcing rib members on the surface. The fatigue detection device comprises: a fixing seat, a fixture and a supporting frame, wherein the fixing seat at least comprises two oppositely arranged fixing plates for fixing a fiber sample strip from both sides; the fixture comprises a rectangular fixing frame and an elastic pressing block, the rectangular fixing frame comprises an upper fixing plate and a lower fixing plate; the elastic pressing block is fixedly connected to opposite sides of the upper fixing plate and the lower fixing plate;and the supporting frame is used for supporting and fixing the fixing seat. Compared with the prior art, the fatigue detection device provided by the invention has the beneficial effect that, in thefatigue detection device with reinforcing rib members on the surface, the elastic pressing block is arranged on the both sides of the fiber sample strip, a fatigue test is performed on the fiber sample strip through the elastic pressing block without using a vacuum suction cup, meanwhile, since the elastic pressing block has certain elasticity, the situation that the middle of the fiber sample strip is not stressed is avoided, so that the accuracy of the test result is ensured.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to a fatigue detection device with reinforcing ribs on the surface. Background technique [0002] With the continuous development of the lightweight trend of high-speed trains, fiber materials have gradually replaced stainless steel materials and become the mainstream of high-speed train components. The equipment cabin is a cabin space located at the bottom of the rail vehicle for placing equipment. Due to the high performance requirements of the train body, the skirt board needs to be tested for fatigue after the completion of the fabrication. Most of the existing fatigue test devices use vacuum suction cups. The surface of the fiber spline is stretched or compressed by the vacuum suction cup for fatigue testing, but the vacuum suction cup can only measure the fiber spline with a flat surface, and the fiber spline with ribs or through holes on the surface cannot use the...
